MOUNTING FOR LETTERS Filed Sept. 15, 1958 INVENTOR, JUJEPH J jlMRCIN United States Patent 3,063,199 MOUNTING FOR LETTERS Joseph J. Marcin, Chicago, Ill., assignor to Spaniel Brothers, Inc., Chicago, 111., a corporation of Illinois Filed Sept. 15, 1958, Ser. No. 761,168 1 Claim. (Q1. 50-23) This invention relates generally to improved means embodying the use of adhesive for securing articles to a wall and, more particularly, to means of this type having supplementary supporting means for holding the wallengaging surface of the article in contact with the wall surface while the adhesive is setting.

A conventional method of securing articles, such as individual letters in a sign, to a wall embodies the use of mounting-pads fastened to the article and atfixed to the wall surface by adhesive. However, it requires a rather lengthy period of time for the adhesive to set or harden sufficiently to secure the pad to the wall. During this interval the pad alone will not support the article and supplementary supporting means must be used.

The usual method for supporting the article during the setting period was to tape it to the wall. This method entailed the additional bothersome and time consuming steps of initially applying the tape and of then removing the tape once the adhesive had dried.

The present invention features a noval type of supplementary supporting means which eliminates the use of tape and which also serves as a permanent additional support for the mounted article. The supplementary supporting means embodied in the present invention comprises a stud or member extending through the wall engaging surface of a conventional mounting pad and securing the pad to an article. The stud is inserted into a hole bored into the interior of the wall. Insertion thereof is to a depth enabling the adhesive-bearing engaging surface of the pad to contact the Wall surface. Adhesive is also applied to the interior of this hole. When the stud is so emplaced it supports the article and pad sufiiciently to maintain the pads engaging surface in contact with the wall, thus eliminating the need for tape. When the adhesive has set the mounted article is supported by the resultingly securely afiixed stud as well as the securely affixed pad.

Therefore, a primary object of this invention is to provide means for mounting articles to a wall by the use of adhesive which means further embodies supplementary means for supporting the article during the time required for the adhesive to set.

An additional object of this invention is to provide mounting means of the type described in which the aforementioned supplementary supporting means serves to provide additional support of a relatively permanent nature once the adhesive has set.

Other objects and advantages are inherent in the structure claimed and disclosed or will become apparent to those skilled in the art from the following detailed description in connection with the accompanying drawings wherein:

FIG. 1 is a perspective view showing one letter of a sign mounted on a wall.

' FIG. 2 is a perspective view of the rear of a letter showing mounting means embodied in the present invention.

FIG. 3 is a fragmentary vertical sectional view of a mounted letter showing mounting means featured in the present invention.

Referring to the figures, the numeral indicates generally a letter of a type conventionally used in signs. Letter 10 is preferably molded of plastic with top, bottom, front and side walls, as shown in FIGS. 1 and 2, but with no rear wall (FIG. 2).

3,063,199 Patented Nov. 13, 1962 ice As seen in FIG. 3, projecting rearwardly (to the right in FIG. 3) from the rear surface 11 of the front wall 12 of letter 10 is a protruding portion .13 adapted to receive one end of a longitudinal threaded member or stud 14. Screwed onto member 14 is a circular pad or disc 15 having a forwardly projecting hub portion 16 and an opening 17 extending therethrough for receiving member 14. Radiating outwardly from the center of disc 15 are a series of spaced holes or perforations 18. Disc 15 is positioned along member 14 .so that when the rear surface 21 of disc 15 contacts the front surfaces 22 of a wall 20, there is a clearance of not less than A; inch between the rear edges 23 of letter 10 and front surface 22 of wall 20.

In order to mount letter 10 onto a wall 20 a hole 19 must first be bored into the interior of wall 20. Hole 19 must have a larger diameter than the diameter of member 14, as illustrated in FIG. 3, for reasons to be subsequently noted. Adhesive 9 is then placed within hole 19 and onto rear surface 21 of disc 15. The adhesive may be of the same type as was heretofore generally used by those skilled in the adhesive mounting art for atfixing articles to wall surfaces. Member 1'4 is then inserted into hole 19 until rear surface 21 is against the front surface 22 of wall 20. Letter 10 is then twistingly moved several times while a rearward, pushing pressure is simultaneously applied. As a result, adhesive 9 spreads evenly along back surface 21 of disc 15 and oozes through holes 18 therein. The aforementioned movement is possible because hole 19 has a diameter large enough to allow the free movement or play of member 14 therein. It is continued until only a thin film of adhesive remains between back surface 21 of disc 15 and front surface 22 of wall 20.

When thus' emplaced member 14 is held during the setting period of adhesive 9 against such movement within hole 19 as would be caused by the natural gravitational pull on letter 10 and the elements fastened thereto. Rear surface 21 of disc 15 is consequently able to maintain its engagement with front surface 22 of wall 20, which in turn assures a substantially permanent engagement therebetween once adhesive 9 hardens. After a period of approximately 24 hours adhesive 9 is sufliciently hardened to securely affix disc 15 to Wall 20 thus providing relatively permanent support for letter 10. In addition the adhesive within hole 19 has also hardened, and, as a result, member 14 provides additional permanent support to letter 10.

The embodiment depicted in the figures has a member or stud protruding from but one mounting pad. It should be understood that the number of studs used depends upon how many are necessary to support the weight of the letter or other article to be mounted.

It is to be further understood that the specific embodiment of the invention shown in the drawings and described above is merely illustrative of several of the many forms which the invention may take in practice and is not to be construed as limiting the scope of the invention as defined in the appended claim which is to be interpreted as broadly as possible in view of the prior art.

I claim:

Mounting means for removably securing objects to a wall by adhesive means, said wall having an adhesive containing recess extending inwardly from its surface, said mounting means comprising: engaging means having at least one planar surface, said planar surface having perforations for bearing adhesive material to enable said engaging means to firmly engage said wall when said adhesive material sets, said engaging means having a threaded portion, a longitudinal threaded member having a first and second end portion, said first end portion with respect to said longitudinal threaded member, said' second end portion being inserted in said adhesive containing wall recess when said planar surface engages the wall surface whereby said engagement between said surfaces is maintained by said second end portion when said adhesive on said planar surface is setting.
